1. An electromagnetic pole for a rotary electric machine with an axis of rotation comprising:
a tooth comprising a tooth body comprising a magnetic material, in particular a laminated tooth body comprising a plurality of steel plate stacked in the direction of the axis of rotation, the tooth being radially oriented and the tooth comprising a recess,
a coil arranged in the recess, the coil comprising a plurality of wire turns wound around the tooth between a first radial end and a second radial end,
the wire turns which are the most distant from the tooth body between the first radial end and the second radial end, forming an outer wire layer,
the coil comprising a bracing wire, the bracing wire being wound on the outer wire layer from the first radial end to the second radial end in less than one turn around the tooth so as to hold in position the outer wire layer.
